Lab Assessment Questions & Answers1. Which tool, Wireshark or NetWitness, provides information about the wireless antenna strength during a captured transmission? Wireshark, under 802.11n MAC +PHY line to expand those fields. That field reveals a large amount of data about the 802.11n connection including signal strengths, noise ratios and other information about the antenna. 2. Which tool displays the MAC address and IP address information and allows them to be correlated for a given capture transmission? NetWitness3. What is the manufacturer specific ID for the GemTek radio transmitter/receiver?Wireshark displays transmitter/receiver addresses in both full hexadecimal (00:14:a5:cd:74:7b) and a kind of shorthand, in this case, GemtekTe_cd:74:7b.
